* space H<sup>div</sup>. These elements generate vector fields with
* normel components continuous between mesh cells.
*
- * @todo Right now, the description of node values and interpolation
- * does not match the actual state of this class. This will be
- * improved after some discussion.
- *
* We follow the usual definition of the degree of RT elements, which
* denotes the polynomial degree of the largest complete polynomial
* subspace contained in the RT space. Then, approciamtion order of
* QGauss<sub>k+1</sub> on each face as well as QGauss<sub>k</sub> in
* the interior of the cell (or none for RT<sub>0</sub>).

- * <h3>Numbering of the degrees of freedom (DoFs)</h3>
- *
- * This paragraph is obsolete and will be removed after reconstruction
- * of the element is complete.
- *
- * Raviart-Thomas elements have their degrees of freedom on edges,
- * with shape functions being vector valued and pointing in normal
- * direction. We use the standard enumeration and direction of edges
- * in deal.II, yielding the following shape functions in 2d:
- *
- * @verbatim
- * 2
- * *---^---*
- * | |
- * 3> >1
- * | |
- * *---^---*
- * 0
- * @endverbatim
- *
- * For the 3d case, the ordering follows the same scheme: the lines
- * are numbered as described in the documentation of the
- * Triangulation class, i.e.
- * @verbatim
- * *---6---* *---6---*
- * /| | / /|
- * 11 | 5 11 10 5
- * / 7 | / / |
- * * | | *---2---* |
- * | *---4---* | | *
- * | / / | 1 /
- * 3 8 9 3 | 9
- * |/ / | |/
- * *---0---* *---0---*
- * @endverbatim
- * and their directions are as follows:
- * @verbatim
- * *--->---* *--->---*
- * /| | / /|
- * ^ | ^ ^ ^ ^
- * / ^ | / / |
- * * | | *--->---* |
- * | *--->---* | | *
- * | / / | ^ /
- * ^ ^ ^ ^ | ^
- * |/ / | |/
- * *--->---* *--->---*
- * @endverbatim
- *
- * The element does not make much sense in 1d, so it is not
- * implemented there.
